Comments: Beam was taken away to tune to Hall B at 23:20; beam returned for the Hall A current calibration at 00:25. 00:35: Saha just spoke with the PD--MCC had accidentally loaded the Moller quad settings rather than the regular Hall A achromatic setting. This explains why the tune was too dirty for an accurate Arc energy measurement. In resetting the magnets MCC located some of their other tune troubles... so at 01:00 the update was 1-1.5 hours down. Neyret made an opportunistic access for Compton during that time. About 02:30 we got a little pulsed beam and tripped a Moller magnet. As of 03:20 MCC has completed their access to reset the magnet and is in the process of bringing it up. CW beam 3uA at 03:55. 05:00: Arc energy measurement finished; setting up for ep energy measurement. 06:10: Finished ep measurement. Starting current calibration. Reference DVM in injector is not stable so couldn't complete measurement. Did a little trouble-shooting of bcm calibration equipment and did a sweet spot scan.
